I've got a question for those that are running or building the BRC 150 engine. I'm running this engine on a laydown enduro kart and had a recent failure where a circlip came out and caused some damage as you can imagine. Pretty much everyone in the enduro community uses spriralocks instead of traditional circlips because they tend to stay put and manage the movement of the wristpin better. The problem is I can't find a source for spiralocks because they need to be 15mm instead of the 14mm used in most all of the other engines we run. Has anyone used sprialocks in their BRC 150 and if so, where did you get them?
As a sidenote I'm using the VHM piston and the wrist pin that comes with it. I've also been using some IAME .045" circlips instead of the thinner circlips that come with the piston.
